CHARLES W. JOHNS, F JERSEYVILLE, ILLINOIS.

SMOKE-CONSUMER.

Application filed February 17, 1913.

To all whom it may concern:

Be it known that 1, CHARLES \V. JOHNS,

' .and useful Improvements in Smoke-Con- 'sumers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in smoke consumers and relates more particularly to improvements over that structure disclosed in my United States Patout No. 1,049,100.

The primary object of the invention resides in the provision of a more effective arrangement of parts than that disclosed in said patent and also in the provision of spreader plates whereby the smoke and gases may be properly distributed over the fire.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete 'understanding of my invention, reference is to be had to the following description and accompanying drawin s, in which,

*igure 1 is a front elevation, showing my improved smoke consumer in 0 rative con nection with a furnace, Fi 2 1s a side elevation, Fig. 3 is a view ta ton on the plane of line 3-3 of Fig. 1, Fig. 4 is a. fragmentary interior View, showing the spreader plates in elevation, and, Figs. 5 and 6 are sectional views taken on the planes of lines 55 and 6 6, respectively, of Fig. 4.

Referring in detail to the drawings by numerals, 10 designates a furnace provided with a fire box 11 and an ash-pit, which compartments are closed by the doors 12 and 13, respectively. A boiler 14 and smoke stack 15 are arranged as clearly shown in the drawings.

A pipe 16 leads from the stack 15 to a blower 17, which latter is mounted upon the boiler '14 adjacent said stack. A downwardly and forwardly inclined pipe 18 leads from the blower to the top of a tank 19. The tank is positioned to one side of the furnace near the front end thereof and is Specification of Letters Patent.

Patented July 4, 1916.

Serial No. 748,964.

connected with the fire box 11 by means of a pipe 20, which enters the fire box above one of the doors 1'2 and which is provided with a branch 21 which enters the fire box above the other door 12. A damper 22 is employed to control the flow of smoke and gas through said pipe.

A pipe 23 extends from the lower end of the tank I!) through the ash-pit and the passage through said pipe is adapted to be closed by a damper 24.

A steam pipe 25 admits steam to the pipe 18 and directs the same downwardly along the longitudinal center of the tank 19. A valve 26 is employed to control the'flow of steam through the pipe 2:). The stack 15 is provided adjacent its upper end with a fresh air opening 27 which is adapted to be closed by the plates :28. The opening 27 is diametrically opposite the forward end of the pipe 16 and is arranged somewhat above the same. A cover plate 29 is hingedly secured to the top of the smoke stack.

It is particularly noted that the arrangement of parts heretofore described, eliminatcs the long connecting pipe between the stack and blower, as shown in my prior patent and provides for a more thorough mixing of the steam and gases. The path of the gases and fresh air as they pass from swing over the openings 31 through which the refed gases are admitted into the fire box. 'lhese plates are hinged at their upper edges by means of the pintles 32 and suitable connections therewith, as is clearly shown in Fig. 4. Adjusting rods are pivot-ally secured to the spreader plates and extend outwardly through openings 34 formed in the front wall of the furnace. These adjusting rods are formed with teeth 35 which engage projections 36 and thereby hold the spreader plates at any predetermined angle with respect to the furnace wall.

It will be seen that the spreader plates are of such a construction and are so positioned as to make it possible to direct the refed gases to any portion of the fire box.

In operation, the cover plate 29 is raised and the fan produces a draft, drawing gases and smoke from the stack 15 and blowing them, together with steam, into the fire box through the means heretofore described.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have provided a smoke consumer which is an improvement over the one disclosed in my prior patent, in that the parts are arranged to a better advantage and that spreader plates are employed for properly distributing the refed gases and smoke.

It is to be understood that While I have shown and described the preferred embodiment of my invention, I do not Wish to be limited to this exact construction, combination, and arrangement of parts, but may make such changes as will fall Within the spirit and scope of the invention.

Having thus described my invention, what I claim is In a device of the character described comprising a furnace having a boiler, fire-box and ashpit, a. smoke stack mounted on said boiler, a blower mounted on said boiler and connected'to said smoke stack, an outwardly and downwardly extending pipe connected Gupta: 0! this patent may be obtained or he cents each,

to said blower, a tank secured to said pipe, means for conducting smoke from the tank to the ash pit, means for cutting off smoke from said ash pit, said furnace provided with openings into the fire-box, a second pipe connected to said tank and provided with branch pipes adapted to extend into said openings, semi-circular spreader plates hinged to the interior of the fire-box and adapted to overhang said openings, said furnace provided with a second lot of openings adjacent said first mentioned openings, rods pivotally secured to said plates and extending through said last mentioned openings, teeth formed on said rods to engage shoulders formed in last mentioned openings, providing means to adjustably support and regulate the angle of the plates in relation to said first mentioned openings for spreading the smoke over a fire in the fire-box and means for conducting steam to the tank.

In testimony whereof I aifix my signature in presence of two Witnesses.
